WEDGE-ADJUSTING DEVICE FOR JOURNAL BOXES.

Application filed December 31, 1920. Serial No; 434,303.

T 0 aZZ w ham it may concern:

Be it known that I, FRANK R. ITARVEY, a citizen of the United States, residing at Blossburg, in the county of Tioga and State of Pennsylvania, have invented new and useful Improvements in Wedge-Adjusting Devices for Journal Boxes, of which the following is a specification.

This invention relates to a wedge adjusting device for the journal boxes of locomotive driving wheels, and the object is to provide for effecting the adjustment of the wedges by the use of compressed air acting on a plunger in an air cylinder.

A further object is toprovide means for mechanically shifting all of the wedges on the sides of the locomotive frame simultaneously, and a controlling device responsive to air pressure, for effecting the result stated.

With the foregoing and other objects in View, the invention consists in the novel construction, combination and arrangement of elements hereinafter described and claimed.

In the drawings,

Figure 1 is a diagrammatic View, from above, showing the air controlling cylinder, a plurality of connecting rods on the sides of the locomotive frame, and a transverse shaft for connecting these rods, the shaft to be rocked by the operation of a plunger in the cylinder;

Figure 2-is also diagrammatic, so far as the relative position of the air cylinder and wedge controlling devices is concerned, the elements last named being in side elevation;

Figure 3 is a detail view of the actuating device, in side elevation, and showing the spring latch.

Figure 4 is a detail view showing the opening provided in member 21,.to be loosely engaged by the reduced end of the element connected with the wedge.

The pedestal 10 of a locomotive'frame includes the legs 12, arranged in pairs, in the usual manner, The adjustment wedges 14 serve the usual purpose in reducing or elimi nating play between the journal boxes 15 and the legs 12. The transverse bar 16 also serves the usual purpose, but operatively connected with each wedge 14 is a pivoted arm or lever 18, including the long leg 19, the element 20 inclined with reference to the element 19, and the laterally extending portion 21. The element 21 is apertured, the apertured portion being engaged by the reduced portion 22 of the wedge bolt 23.

A connecting rod 24 is pivotally connected at the point 25 with each member 19, and is designed to operate all of the pivoted arms or levers 18, on the sides of the locomotive. The pivotal mounting of each arm 18 is designated 26.

An air valve 30 to be placed in the engineers cab has connectionwith the cylinder 31, so that the engineer may be able'to admit air to the cylinder for the purpose of operating the plunger 33 therein, the stem I of the plunger having connection with a pivoted arm 35, on shaft 36 and pivoted to the connecting rod 24. The engineer may thus control or set up all of the wedges in one operation, wedge bolt 23 and latch 30 maintaining the adjustment secured.

What is claimed is 1. The combination with a wedge for setting up a journal box, to compensate for wear, of air controlled means for imparting movement to the wedge.

2. The combination with a edge for setting up a journal box, of an air cylinder and plunger therefor, and means connecting the plunger and wedge.

3. The combination with a plurality of wedges for setting up journal boxes, of an air cylinder and plunger therefor, a rod controlled by the plunger, and pivoted elements connected with the rod and acting to control the position of the wedges simultaneously.

4. The combination with a wedge for setting up a journal box, of air controlled 'means for imparting movement to the wedge,

and mechanical means for maintaining an adjusted position of the wedge.

In testimony whereof I aflix my signature.

FRANK R. HARVEY.
